A. Examine the variable partnrs5 (number of sex partners in the last five years) in the GSS2018 data set. Assume that a previous set of studies (all at least 5 years prior) indicate that the mean number of sex partners in the previous 5 years was 1.9. A social scientist at the CDC claims that numbers of sex partners have declined, diminishing one dimension of risk for contracting sexually transmitted diseases or unwanted pregnancy. Using the SPSS one sample t test, test the appropriate null hypothesis against the research hypothesis suggested by the CDC social scientist using the .01 alpha level. Identify the null hypothesis, research hypothesis, critical value and test statistic. Explain your results. Please report or include elements of the SPSS output you utilized for your hypothesis tests. Hint: you will need to adjust both the test value (which is the test mean) and the confidence interval according to the alpha value in the assignment.
